SPEQIFIGATION formingpart of Letters Patent No. 752,793, dated February 23, 1904.

Application filed Junelfi, 1902.

To all whom it may concern:

Be it known that I, HIDALGO MOYA, (cornmonly known as DALGO MoYA,) inventor, a citizen of the United States, residing at 67Western road, Leicester, in the couuty'of Leicester, England, have invented certain new and useful Improvements Relating to Type-Writing Machines, of which the following is a specification.

This invention relates to improvements in type-writing machines, and has for its object to devise simple, durable, and efiicientmechanism which, while adapted to move the paperroller carriage with a step-by-step movement as the type key-levers are operated, is capable of permitting 'the paper-carriage to be pushed rapidly by hand in both directions. Of course the pawl must beswung out of the way when the carriage is so pushed.

According to this invention the paper-carriage is provided with a rack -,,bar having ratchet-teeth which are masked by a. plate, which plate is carried by the papencarriage support and has a gap situated about midway the inclined end of the gap in the mask-plate.

The pawl when moved on its axis has thus a motion along that axis, so that its nose moves sidewise away from the rack and is automatically held'clear of the rack by the mask-plate vided with my invention.

I l elevation of the rack-bar, mask-plate, spring when the pawl is on its backstroke, 'so as to permit the paper-carriage to freely move to the right or to the left of the machine.

Referring to the drawings, Figure 1 is a side elevation of a type-Writing machine pro- Fig. 2 is a front pawl, and part of the paper-carriage support. Figs. 3 and 4; are horizontal sections on the "serial No. 111,805. (No model.)

line A B of Fig. 2. I Fig. 5 is afront elevation of part of the mask-plate clearly showing vided with an opening or gap 9, which hasan,

incline '10 at one end and which permits the nose 11 of a pawl 12 to pass through the Aboutv mask-plate and'engage with the ratchet-teeth 7, the straight side of the nose 11 facing toward the straight side of the ratchet-teeth and "the inclined side of the nose 11 facingtoward the incline 10 and toward "the inclined sides of the ratchet-teeth. The pawl 12 is'adapted to rock angularly about and also to move along'a pivot-13, carried by the support 5. A spring 14. tends to hold the pawl 'in the position shown in Figs. 2 and3, anda spring 15 tends ,tohold pawl 12 flat against plate 8.

When one of the type key-levers 16 is op- 'erated, as is well understood, it raises the inner end of a frame 17, pivoted at 18, thereby depressing a foot 19, carried by the frame17.

This foot 19 bears upon the lower arm'of the pawl 12, thereby rockingsaidipawl about the pivot 13 and against the resistance of the spring 14, thus causing the inclined side of the .nose ll'to bear against the inclined side of oneof the ratchet-teeth 7, so as to move, the pawl 12 outwardly along its pivot 13' against the resistance of the spring 15 untilthe nose 11 comes into contact with-the incline 10 on the rightof gap 9. When foot-19 is released,

spring 14 rocks pawl 12 on its pivot 13, and spring 15 simultaneously moves pawl 12 toward plate 8, and nose ll'engages one of the "ratchet-teeth and feeds thepaper-carriage one step toward the left of the machine. When nose 11 of .pawl 12 isin engagement with incline 10 of plate .8, the paperrcarriage can be.

pressed by hand in either direction, foreven if nose 11 should not be entirely clear of the ratchet-teeth 7 when pushing the paper-carriage byhand toward the left of the machine the inclined sides of the ratchet-teeth 7 bear against the inclined side of the pawl-nose l1,

and thereby throw the pawl out ofengagement with the rack-bar against the resistance ofthespring 15, and when the paper-carriage is pressed by hand toward the right of the machine, Figs. 3 and 4, the straight side of the ratchet-tooth 7, with which the nose 11 is in engagement, forces the inclined side of said nose against the incline 10, and thereby teeth when moved to the right will swing pawl on its axis 13, and thereby move the pawl sidewise along axis 13 until the nose 11 is'c'arried clear of the ratchet-teeth, andthe action of the inclined sides of the ratchet-teeth when an inclined h1g9 vent the moved to the left, with the nose of the pawl projecting slightly through gap 9, will move pawl 12 along its axis 13 against spring 15 whenthe nose 11 of pawl 12 is nearly in the position shown in Fig. 4,-but not wholly clean of the ratchet-teeth 7 A-fspring 20, secured to the plate 8, carries a \lshaped-tooth 21, which passes through an opening 22,- Fig. 5, in the plate 8, and engages with, the ratchet-teeth 7 in order to prepaper carriage being accidentally shifted in the wrongdirection when the keyleversare operated.

Ipreferably provide to'serve as a guide to the pawl 11, for although-the nose 11 ismoved away from lug 9 when the pawl 12 is swung on its axis (see Fig. 4) by sliding over the inclined end of the ratchet-tooth 7 and thereafter by sliding over the incline 10 at the end of gap 9, yet when pawl 12 is swung on its axis 13 by the force of spring 14 the incline on lug 9 makes certain that nose 11 shall be always retained in proper contact with the straight side of that ratchet-tooth on which it is then acting, thereby aiding spring 15 to perform its function of pressing pawl 12 close against plate 8.

What I claim, and desire to secure by Letters Patent of the United States, is

1. In a type-writing machine, the combination with the key-levers and the paper-carriage, of a rack-bar carried by the paper-carriage, a fixed plate provided with an opening and masking the teeth of the rack-bar, a pivpawl 12 benot wholly clear the mask-plate 8 with oted pawl which passes through the opening in the mask-plate and engages with the teeth of the rack-bar, means which tend to hold the pawl against one end of the opening in the mask-plate, and means operated by the keylevers for rocking the pawl about its pivot to feed forward the as described. I

' 2. In a' type-writing machine the combination of the pivoted key-levers, the paper-cylinder, the frame in which said paper-cylinder is journalcd, a rack-bar carried by the papercylinder frame, a fixed plate provided with an opening and masking the teeth of therackbar, a pivoted pawl which passes through the opening in the mask-plate and engages with the teeth of the rack-bar, a spring which tends to hold said pawl against one end of the opening in the mask-plate, and means operated by the key-levers for rocking the pawl about its pivot to feed forward the paper cylinder frame, substantially as described for the purpose specified.

3. In a type-writing machine, the combination of the pivoted key-levers, the paper-cylinder, the transversely traveling frame in which the paper-cylinder is journaled, a rackbar carried by the paper-cylinder frame and the teeth of which each have a straight side paper-carriage, substantially and an inclined side, a fixed plate which masks i the teeth of the rack-bar and has an opening provided with a beveled side, a pawl having a nose provided with a straight side and an inclined side, the straight side of said nose engaging with the straight sides of the rackteeth and the inclined side of said nose facing the beveled side of theopening in the maskplate, a fixed pivot about which the pawl can both rock and move longitudinally, a spring which tends to hold the nose of the pawl against the mask-plate, and means operated by the key-levers for rocking the pawl about its pivot to feed forward the paper-cylinder frame, substaintially as described for the purpose specifie 4. In atype-writing machine,'the combination of the jpivoted key-levers, the paper-car- IIO riage, the transversely-traveling frame in which the paper-cylinder is journaled, a rackbar carried by the paper-cylinder frame and the teeth of which each have a straight side and an inclined side, a fixed plate which masks the teeth of the rack-bar and has an opening provided with a beveled side, a pawl having a nose provided with a straight side and an inclined side, the straight side of said nose engaging with the straight sides of the rackteeth and the inclined side of said nose facing the beveled side of the opening in the maskplate, a fixed pivot about which the pawl can both rock and move longitudinally, a spring which tends to hold the nose of the pawl against the mask-plate, a frame pivoted to the machine and adapted to be rocked by the keymy hand, in presence of two subscribing witlevers, and ahfoot earriedfhyilsaid fralglle ancill nesses, this 17th day of May, 1902. engaging Wit one arm 0 t e pivote paw for moving said pawl against the resistance of HIDALGO MOYA' 5 the spring, substantially as described for the Witnesses:
